Product Usage Instructions

1. Turn off all power supplying this equipment before working on or inside equipment.
2. Use a properly rated voltage sensing device to confirm power is off.
3. Remove the handle extension (d).

Visi-Trip Functionality: The Visi-Trip LED handle aids in quickly locating a circuit breaker that requires attention. Inspect the handle position for circuit breaker trip indication. The Visi-Trip handle will flash an LED light as described in Table 1.
Note: When performing annual maintenance in accordance with MCCB Field Testing and Maintenance Guide (0600IB1201), operate the push to trip button (if equipped) to verify the Visi-Trip functionality. Cycle the circuit breaker from tripped to OFF, and then from OFF to ON and take note of the battery health. See Table 2. Wait five seconds between handle operation and push-to- trip button operation to ensure that the Visi-Trip handle is on standby mode. Tripping the circuit breaker too soon after toggling may result in the Visi- Trip handle not operating as intended.

Enclosure Clearances:  Install circuit breaker so minimum clearance distance to grounded metal is maintained. Refer to Figure 2 for enclosure clearances and the use of a fiber insulating plate.

3. Use a properly rated voltage sensing device to confirm power is off.
4. Remove the handle extension (d).

Visi-Trip™

The Visi-Trip LED handle aids in quickly locating a circuit breaker that requires attention. Inspectthe handle position for circuit breaker trip indication. The Visi- Trip handle will flash an LED light as described in Table 1.
Note: When performing annual maintenance in accordance with MCCB Field Testing and Maintenance Guide (0600IB1201), operate the push to trip button (if equipped) to verify the Visi-Trip funcitonality. Cycle the circuit breaker from tripped to OFF, and then from OFF to ON and take not eof the battery health. See Table 2. Wait five seconds between handle operation and push- totrip button operation to ensure that the Visi-Trip handle is on standby mode. Tripping the  circuit breaker too soon after toggling may result in the Visi-Trip handle not operating as intended.

TABL.1:

the handle position for circuit breaker trip indication. 1

1. Refer to the Schneider Electric Frequently Asked Questions page. https://www.se.com/us/en/faqs/home/for. more information. /
2. If a nuisance LED flashing occurs on ON or OFF position, it can be reset by toggling the circuit breaker. If toggling the circuti breaker is not desired, LED flashing will reset after six hours.

Individually-Mounted Circuit Breaker Installation

DANGER: HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH Install circuit breaker so minimum clearance distance to grounded metal is maintained. Failure to follow these instructions will result in death or serious injury.

1. Check the electrical clearances (Figure 2, a). Insulate the circuit breaker if necessary (b–c).

Enclosure Clearances

Fiber Insulating Plate

Enclosure Dimensions

J-Frame Enclosure Insulation2

1. If dimension “A” is less than 0.56 in. (14.2 mm), attach fiber insulating plate (not provided) to enclosure cover.
2. Insulation required if circuit breaker side is < 4.13 in. (105 mm) from metal.

Install the circuit breaker

I-Line™ Circuit Breaker Installation

NOTICE
HAZARD OF EQUIPMENT DAMAGE

• Do not adjust jaws.
• Do not remove joint compound.
• If necessary, use Square D joint compound PJC7201.

1. Rack the circuit breaker onto the bus (Figure 4 (a–c).
2. Tighten the mounting bracket screw (d–e).

Cable Installation

Note: If the circuit breaker has terminal nuts installed, remove terminal nuts and install lugs as directed in the instructions shipped with the lug kit.

NOTICE
HAZARD OF FALSE TORQUE INDICATION Do not allow conductor strands to interfere with threads of wire binding screw. Failure to follow these instructions can result in equipment damage.

TABL.2: Lug Information

Conductors must be cut square for secure termination
Note: See Table 2 for strip lengths and torques.

1. Preform the conductors to their final configuration. Strip the conductor ends (Figure 5, a). Do not nick strands.
2. Install the cables in the lugs and torque the wire binding screws (b–c).
   • Install wire larger than 12 AWG in the center of the channel (d).
   • Install 14–12 AWG wire on the side of channel (e) on all lugs to avoid damage to the wire.

Bus Installation

Note: If terminal nut inserts are not installed, install the terminal nut inserts as directed in the instructions shipped with the terminal nut kit.
